Abstract:This paper focuses on heavy metal. A geological environmental model is established on the basis of analysis of systematic field sampling. Factors affecting environment include: Gejiu primary mineral is rich in multi-metal sulfide, which is easy to become acid as the result of oxidation. Carbonated salt can consume acid produced in the process of oxidation of sulfide and stop transfer of metal. Weight of metal emitting to the environment from the ore bed prior to development: 12, 100 tons of Cu, 70, 000 tons of Pb, 101. 96 tons of Cd, 12, 000 tons of As, and 23, 300 tons of Sn. Technological process of float-heaviness is adopted in ore-dressing of cassiterite-sulfide, and water environment in Gejiu Mine is generally in good condition. Heavy metal elements in such comparison areas as Kafang, Niushipo, and Yunxi are several time higher than the State Standard of Class C Land, and it is cuased by mining, ore-dressing and smelting. Dust emission of Refining Works of Yunxi Group has becomes one of the main sources of heavy metals. After recultivation on Taihungshania in Niubahuang, Taihungshania indeed affects surface soil.
Keywords:Potential Factors of Affecting Environment  Prior to Mine Development  After Closing of Part Function  Mineral Geological Environment Model  Gejiu
